What is one potential effect of adverse weather on train operations?

One potential effect of adverse weather on train operations is its impact on track safety. Adverse weather conditions, such as rain, snow, ice, and extreme temperatures, can affect the integrity of the tracks and the surrounding environment. For instance, heavy rain can lead to flooding, which may wash away track foundations or create unstable conditions. Snow and ice can accumulate on the tracks or in critical mechanisms, leading to potential derailments or failures of signaling systems. Therefore, ensuring track safety amid such conditions is paramount for the safe operation of trains, ultimately to prevent accidents and maintain the reliability of the rail system.

In contrast, while adverse weather can influence various operational parameters, it doesn't directly impact the sound of the train or lead to changes in ticket prices. Additionally, while it might affect train speed limits, the primary and most immediate concern is ensuring the safety of the infrastructure on which the trains operate.
